Where is libmysqlclient?

I do compile the Percona 8 like below but cannot find where is libmysqlclient. i can see it in 5.7.

I got issues with Xtrabackup " XtraBackup Complains of Missing perl-DBD-MySQL" and other tool like Zabbix when i compile, it always ask for libmysqlclient

Is this lib include on source package or i need to yum or compile from other souce?

Have you tried searching for it? find /usr/ -name "libmysqlclient*"

Hi Matt,

That is first cli that i tried to find before i post this forum :slight_smile:

I cannot see this lib from mysql 8 version

[root@localhost ~]# find / -name libmysqlclient*
[root@localhost ~]# mysql -V
mysql  Ver 8.0.25-15 for Linux on x86_64 (Source distribution)

Just wonder if i install this lib by download rpm package from mysql community then is that compatible with Percona or not?

Well, you need to decide if you want to compile Percona MySQL 8 and use that, or use our RPMs. Why are you compiling? Also, why would you download mysql community rpm for this library? Why not download the percona library rpm?

I want to use Percona server and yes with compile, after compile that i cannot find libmysqlclient so that is a reason why i ask for install this lib by rpm from mysql community version.

Yes, i forget Percona may have this rpm but just wonder why i cannot see this lib after compile or i need to install separately and if i do so then do it conflict to my server?

@abh I just did a compile and I found the library. I’ll have ask one of the developers why it isn’t named libmysqlclient, but I imagine it is safe to simply create a symlink and then run an ldconfig before linking against it.

Hi @abh.
Yes we compile libperconaserverclient.so by default.
In our rpm packages we still provide libmysqlclient.so.
So if you need to compile by yourself you could apply patch percona-server/mysql-5.7-sharedlib-rename.patch at 8.0 · percona/percona-server · GitHub and it will compile mysqld linked with libmysqlclient.
Also we recommend using our build script to compile PerconaServer for MySQL by your own.
Here it is: percona-server/percona-server-8.0_builder.sh at 8.0 · percona/percona-server · GitHub
How to correctly use it you can read in our blog: How to Build Percona Server for MySQL From Sources - Percona Database Performance Blog

Hi @Evgeniy_Patlan ,

Can you guide me how to “apply patch and it will compile mysqld linked with libmysqlclient.” ?

@abh, download the .patch file that Evgeniy linked above. Use the patch utility to apply the patch to your code tree, then compile as usual.

You had failures applying the patch file. You must make certain that the patch file you downloaded exactly matches the branch/code version you have.

Why don’t you just download the pre-compiled binaries and create a symlink to libmysqlclient? That will instantly solve your issue.

@matthewb ,

If “yum” direct from Percona then i see the libmysqlclient but im not seeing any libperconaserverclient. It’s bit strange if you ask me

You are saying “Why don’t you just download the pre-compiled binaries and create a symlink to libmysqlclient”, is that means i still compile as the way i want then download client with rpm version then job done?

No. “pre-compiled” means that we (Percona) have already compiled it for you and it is ready to work.

Appreciated your support @matthewb . Im testing performance pre-compile version vs with my manual compile
